Abstract (en)
[origin: US2015264123A1] A device in a peer-to-peer (P2P) group has the role of group owner. A different device in the P2P group may take on the role of group owner without ending the P2P group and create a new P2P group. Multiple P2P groups may be merged into a single P2P group. A single P2P group may be split into multiple independent P2P groups, each with its own group owner. A group owner of a P2P group may notify the client devices in the P2P group that it is about to leave the P2P group. A client device in a P2P group may be appointed in a new role of backup group owner, to take on the role of group owner in the event of a departure of the group owner, thereby providing continuity. Techniques for maintaining upper layer continuity through changes in topology of P2P groups are disclosed.
